cubic expression
2.Abstract: Based on the concept of space migration length of photo-activation species,the analytical expression of the total number N of photo-activation species that can reach a segment on the substrate in the cubic deposition reaction space is derived.The simulation of the relationship of deposition rate and position of substrate is also completed.The simulation result agrees with the experiment data well.
3.In this paper, based on the mathematical expression of Bezier Curve,the ma trix form of quadratic and cubic Bezier curve and the properties of the Bezier Curve,the ap pilication of Bezier Curve in the making of the outline of Chinese character is discussed by combining the internal structure of spdos curve Library and Turbo C program.
